Browser extension
Register and verify content directly from your browser — no need to visit the website every time. Available for Chrome and Firefox.
Also works with Edge, Brave, Arc, and other Chromium-based browsers (use the Chrome version).
What it does
Register from any page
Select text on any web page, right-click, and register it instantly. No copy-pasting required.
Check page content
Click the extension icon to check whether the current page's text matches any registered works.
Publish detection
When you're about to publish on Medium, WordPress, or Ghost, the extension reminds you to register first.
Install on Chrome
Works with Chrome, Edge, Brave, Arc, and any Chromium-based browser. Not on the Web Store yet, so you'll load it manually — takes about a minute.
Download and unzip
Click Download for Chrome above and unzip the file to a folder you'll keep (e.g. your Documents folder). Don't delete this folder — Chrome needs it.
Open the extensions page
Go to chrome://extensions in your browser, or click the three-dot menu → Extensions → Manage extensions.
Enable developer mode
Toggle the Developer mode switch in the top-right corner of the extensions page.
Load the extension
Click Load unpacked and select the folder you unzipped in step 1. The Keep Digital Human icon should appear in your toolbar.
Add your API key
Click the extension icon and enter your API key. You can generate one from your API keys dashboard. This connects the extension to your account so registrations appear on your dashboard.
Install on Firefox
Requires Firefox 109 or later. Not on Mozilla Add-ons yet, so you'll load it as a temporary extension.
Download and unzip
Click Download for Firefox above and unzip the file to a folder you'll keep.
Open the debugging page
Type about:debugging#/runtime/this-firefox into Firefox's address bar and press Enter.
Load the extension
Click Load Temporary Add-on, then navigate to the folder you unzipped and select the manifest.json file. The extension icon should appear in your toolbar.
Add your API key
Click the extension icon and enter your API key from your API keys dashboard.
Note: Temporary extensions in Firefox are removed when you close the browser. You'll need to reload it each session until we're listed on Mozilla Add-ons.
Requirements
- Google Chrome, Firefox 109+, or any Chromium-based browser (Edge, Brave, Arc, etc.)
- A free Keep Digital Human account
- An API key (generated from your dashboard)
